soak your keyboard in warm bath water for about an hour....then tie it's cord to the shower head. It should be hanging so that all the water pours out from one side. After about an hour or so...hit it with some compressed air to get anything out from under the keys...let it sit some more. You want to be certain that there is no moisture left in there before plugging it back in. (I've known some to use a hair-drier to speed up the process).

Just FYI: the air cleaning didn't work and the same keys are not working. I didn't try the "deep cleaning" method....It's a laptop keyboard, so I would have to take the keys out which I don't know how to do. Plus, I'm not sure that giving a keyboard a shower and hanging it on the line to dry is in the Betty Crocker list of approved cleaning methods. Then again, it may very well be. Anyway, that's the whole story.

Do you know for a fact that you spilled something on it? If not, let's run some scans and eliminate spyware as the cause. Many infections don't show up in a HijackThis log.

I know you can take the keys off keyboards and wash them out but I wouldn't go so far as to soak it. I've read that it's not recommended to remove the keys from laptops but can't remember the reason. Perhaps they are more delicate. Laptop keyboards can be replaced as well.

As you deleted your HijackThis log, please remind me what OS you are running before we proceed.

Ok well I just purchased a 2nd hand TwinHead laptop with a broken harddrive and faulty keyboard. To fix the keyboard I pulled all of the keys off (you might wanna be carefull here, take one off, study it, and figure out how to put it back on befor taking them all off ) Then I carefully removed the rubber layer (your board might be different so I'm not sure if it will have the same layers as mine... the important thing is to get to the plastic circuit board unerneath.) It took me a while to spot the fault on mine... it seems that some of the conductor on the bottom layer had been corroded by something (coffee?) The corrosion was only visible from one side and I had to look very carefully to notice the slight discolouration in the tracks.
Once I had done a few continuity checks with the multimeter (testing between the the connector and pads and between pads and other pads on the same wire) I was able to confirm that this was where the fault was...

I basically just scrapped away small sections of insulation (VERY CAREFULLY) on each end of the fault ( use a multimeter to test that there is exposed conductive material.)
Then I drew a line beween the two sections with conductive pen, waited 20 mins, then tested if the pads were working properly.

It took me a couple of tries with the conductive pen and there were two faulty tracks next two each other wich meant that I had to scratch a line between them afterwards with a screwdriver to make sure they weren't connected together.

I'm just about to put the keyboard back in so I'll let you know how it goes...
